MIXER.

Specification of Letters Patent.

Patented Sept. 2, 1919.

Application filed April 5, 1917, Serial No. 160,059. Renewed February 1, 1919. Serial No. 274,570.

To all whom it may concern:

Be it known that I, HARRY E. TRAGER, a citizen of the United States, and resident of Arcanum, in the county of Darke and State of Ohio, have invented certain new and useful Improvements in Mixers, of which the following is a specification.

This invention relates to charge forming devices and has more especial reference to 10 an improved suction control feed means for the device, whereby the supply of air and gas to the charge will be governed by the velocity at which the engine is operating.

It is the dominant object of the invention to provide a charge forming device employling natural or artificlal gas having a novel form of air and fuel feeding means, the

same being. connected and operable syn chronously by suction created by the engine at times and by manual operable means at other times.

Another and equally important object of j the invention is to arrange the air intake means in amanner to permit independent adjustment of the same to regulate the inflow of air upon operation thereof by the engine suction.

It is also an provide means for supplying and discharging the fuel in jet like form into the charge forming chamber of the device.

Other and further improvements and novel details in the construction and arrange. ment of parts will be appreciated from the description to follow, which for a clear understanding of the invention should be considered in connection with the accompanying drawings forming a part hereof and wherein the preferred embodiment of the invention is shown for the purpose of illustration.

In the drawings:

Figure 1 is a vertical longitudinal section through the improved charge forming device;

Fig. 2 is a fragmental section showing the air intake cylinder in detail; and

Fig. 3 is a detail in bottom plan of the air intake cylinder.

Similar characters of reference are employed in all of the above described views to indicate corresponding parts...

Referring now more specifically to the several figures of the said drawings, there is provided a casing element designated 1,

forming chamber thereof the said casing being provided with intake and outlet or exhaust ports in the upper portion thereof axially of the casing and disposed in alinement, the usual butterfly type of control valve designated 2 being arranged in the exhaust port and controlled from the seat of the vehicle or other structure in which the device is arranged.

A fuel supply conduit 3 located axially of the casing 1 atone side is extended from a suitable gas reservoir to a point inproximity of the casing 1 and is provided with a downwardly curved branch discharge pipe 4, the outer extremity of which is reduced and perforated as at 5 and .is received through the lowermost part of the casing 1 adjacent to the wall thereof, the top or perforated side being flat as shown.

A cylindrical valve chamber 6 is secured to the end wall of the casing 1 at a point adjacent the upper intake port by brazing or like processes and has formed in the bottom thereof a tapered slot or way 7 extending from a point spaced from the outer or lnlet end thereof and enlarging to its inner or discharge end. Loosely arranged about the cylindrical valve chamber 6 is a housing 8, which housing has its bottom object of the invention to the opposite extremity of the rod extending therefrom and adjustably connected with a gas supply control valve 14: which will be subsequently described. Obviously, movement of the slidable disk valve 12 over the tapered way 7 formed in the valve chamber 6 will serve as efficient means for controlling the passage of air therethrough into the casing or suction chamber 1.

To control the. supply of gas to the discharge pipe 1, a solid cylindrical valveli is slidably positioned therein and is provided with a screw threaded opening in its outermost end whereby the complementally threaded extremity of the connecting rod 13 may be turned into engagement therewith and as a consequence, ".synch'ronous finove-w ,same together with the disk va1ve*12 may engaged with a slidable rod '20 passing through'an'apertured bearing 21 securedto "o-peratingvconnectlon 22 is engaged with the 0' moved to positions to permitthe flow of su t quence, in the casing .1. Such suction will be operated independently of ithesuction operation means, at times.

Upon the upper side of the supply con-' Jduit 3 there is 7 arranged an apertured lug A '16 havlng a tension screw- 17. passing th'ere I "through, the said tension screw being "=1 a. spring 18,'the-.rema1n1ngend of wh1ch 1sengaged with I one-end of a contractile coiled "nection il -operating in a slot 11 in the cas- ,t a

"formed in the valve chamber 6. It m y fly valve 2. Should the speed of the'engin'e beincreased or decreased, the suction created thereby'will accordingly be increased or decreased, and Will cause the automatic adjusting of the valve 12 and consequently, the valve 14. Thus the supply ofqfuel to the engine cylinders is automatically controlled.

To regulate --thea'-richness -of-the comsecured to ;the connecting rod '13,: thereby,

inatically controlled.

A lever 19 is plvotally secured to the dis-"* charge pipe 4 and has its uppergend pivotally i (serving as meansfor normally maintaining" the several valves, namely, the valves 12 and 14 normally "in closed position, 'Byvarying' the positioning of the tension screw 17 with 1 relation to theapertured lug 16, thetension" of the coiled.spring 18 maybe varied and the movement of the valves 12- and 14 auto-' l ksuch modification as is Within the scope of consider within-the spirit of a the, underside of theisupplypipe- 3. An

movement of the valves; 12 and "14 to open bustible charge, the casing 8 as rotatably mounted upon: the cyl-indrical valve chamber 6 maybe moved by ni'ea'nsof-the conmg 1 tocauseflnovement of the" way 9 forined therein with relation of the Way 7 here noted, that the tapered formation'of the Ways? an'd 9 formed inthe chamber 6 and i casing 8 serve-toalloW theprop'er intake of air when the-engine is-running at high speed, since, the 'suctlon created bythe engine Wlll be greater and therefore will move I the d sk valve inwardly, to a greater extent.

Man festly, the construction shown is any invention.
